Emails going astray, so can't delete blog

I wish to delete one of my blogs, which is no longer valid, but I am not receiving the email to confirm deletion. It is not going into my spam folder or anything like that. Also, despite having the boxes ticked to inform me when comments are made, etc., emails for that are not coming through for my other blog either.

The only thing I can imagine is that it is sending the emails to the address with which I originally set the blog up (which I closed some time ago), but I can't find that email address listed anywhere in my profile, settings, user tab or gravatar. They all have my correct email address. Any ideas?
